Calcaneal fracture closed compression reduction device

Abstract

The invention discloses a closed pressurized resetter for calcaneal fractures. The closed pressurized resetter for calcaneal fractures comprises an "凵"-shaped bracket, a transverse reset device for the width of the calcaneus fixed on the left and right sides of the "凵"-shaped bracket, and a " The calcaneus height correction device at the bottom of the "shaped bracket; the calcaneus height correction device includes a longitudinal adjustment screw, a longitudinal pressure assembly and a longitudinal fixation assembly; the calcaneus height correction includes a longitudinal adjustment screw, a longitudinal compression Components and longitudinal fixation components; the technical solution of the present invention adopts a three-point relative pressurization structure, and the left and right two calcaneus width transverse reset devices are parallel and relatively pressurized on both sides of the calcaneus waist to correct the calcaneus width. The bone height correction device is placed on the subcalcaneal tubercle of the plantar bone to correct the height of the calcaneus and the articular surface under the talus. The structure is scientific and reasonable, and it can simultaneously reset and correct the width deformity and height dislocation of the calcaneus according to the patient's calcaneus fracture. , convenient adjustment and control, safe and reliable, making the closed reset operation more standardized.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a calcaneal fracture closed and pressurized reducer for closed and pressurized calcaneal fracture reduction. Background technique [0002] Calcaneal fractures are the most common tarsal fractures, because calcaneus fractures can seriously damage the calcaneal joint, causing adhesion and stiffness, as well as bone spur formation and calcaneus malunion, etc., which may leave pain and motor dysfunction in the affected foot. Entry into the articular surface or poor reduction, post-traumatic arthritis, and pain during calcaneal weightbearing are common. Currently, the surgical options for calcaneal fractures are mainly open reduction and internal fixation and minimally invasive closed reduction and internal fixation. No matter what method is adopted, the width and height of the calcaneus must be restored. However, in the current clinical work, the most common devices for reducing the f...

Problems solved by technology

No matter what method is adopted, the width and height of the calcaneus must be restored. However, in the current clinical work, the most common devices for reducing the fracture of the calcaneus are manual reduction or support rods to reduce and fix the width deformity on both sides of the calcaneus. , it is still not possible to reset and correct the height of the calcaneus at the same time. When the width is reset, manual reset often fails to achieve the effect due to insufficient strength. If the support rod is used to clamp the reset, the shape of the pressure head is too flat or too sharp , easy to cause damage to the calcaneus, it is difficult to achieve a satisfactory reduction effect
